How I can calculate total number of jpg files upload in form and the nu

How I can calculate total number of jpg files upload in form and the number that still remains to add 100 files. I want to make a form for printing photos up to 100 files.

Hi Antonio,

Thank you for reaching Jotform Support.

That is only possible with a single file upload field, the Multiple Files option set to OFF.

You will also have to add an additional field for each upload field and set a condition to pass value 1 to a field if the upload file is filled.

You can then perform a calculation.

Also, please note that you can hide the fields with passed values. 

Hope this meets what you are looking for.
